It might die well due to the bug. Or not. Did you boot with "quiet" in cmdline?
Can you see any messages if not? Or any chance it managed to store the kernel
messages into the journal? Or would it be possible to boot with init=/bin/bash
and look into the dmesg directly (I am not sure if it's not too late -- perhaps
boot with rd.break, but that might be too late too)? 

But you at least confirmed 6.11.0 is ok and 6.11.2 is not. What about 6.12? And
I've just pushed 6.11.4 -- still the same?

Sorry, but I am not clever from this bug at all.
